‘If we lose each other, then we'll come back to this spot, on this day, at this time, every year until we find each other.'

Casey Miller-James works hard, plays hard and loves hard. She has her dream job in a London art gallery and is busy planning a wedding to her influencer girlfriend who's determined to have the best lesbian wedding anyone has ever seen. Life is good. So why does Casey feel like her heart belongs to that woman from Melbourne she met in Berlin eleven years ago and never saw again?

Holly Craddock feels like life is passing her by. Her career is going nowhere, and her spare time is spent running around after her unappreciative partner and worrying about her mum's illness. She longs to rediscover her passion for photography, and she dreams of finding that woman from London who broke her heart in Berlin so long ago. She doesn't care how brief their romance was, if she's ever going to move on, she needs closure.

When a work opportunity gives Casey time alone and an unexpected event gives Holly the chance to shape her future, they both find themselves asking, ‘what if?' After all, the intense chemistry they once shared must mean something. But how do you find someone from the other side of the world when you only know their first name, and the only plan to reunite was to meet in a Berlin park in late August at 6 pm, eleven years ago? Even if they do manage to find each other, can they make something work in the real world?
